Question

1. What actions does the operating system take when a program issues the open and close operations for a file that is to be read from disk? For a file that is to be created? (There are several actions that take place. The textbook is a better source than Google for this question and most of the others. The book will tell you about "open." From there, you should be able to figure out "create" and "close.")

2. Moving a file to a different directory on the same disk does not require making a new copy of the data in the file. Explain why not. What does happen when a file is moved from one directory to another on the same disk?

3. Explain in detail what is meant by the working set of a process. (Use the textbook! What's on the Microsoft web page is wrong, and will get you a zero on this part of the assignment.)

4. The process dispatcher of an operating system keeps running, ready and waiting queues. Describe what happens with respect to those queues when a running program requests an I-O operation from the operating system, and when the I-O operation completes.

5. Identify four things that you either did not know before taking this class or that you learned something new about as a result of taking the class. (I just want a list of four things, not a book.)

6. Pick one of the four things that you listed in Part 8 and, in two or three paragraphs, tell how the coverage of that subject could be improved.

7. Tell at least one thing, more if possible, that you expected to get out of this course, but did not. (Please note: I'm asking for help to improve the course. A list of things that were missing is much more useful to me than a statement that the course was perfect in every way.)

Any operation in the in service system needs to follow some detailed ways.In a operating organization multiple process and clothes are administration at a time.
So when a process is leaving on if you want to open or close a file after that the current process is stored somehow so so as to it can be constant later on.
The PCB loads the recent address and excutes the tuition like aperture or closing the file.
After the progression is completed the stored talk to is bought to the PCB so that it can restart the execution of the up to that time stopped process.
When a file is shaped the curent procees is stored. The PCB exude the instruction by allocate memory to the file so that it can be accessible to the disk.And then continue with congested instruction
